In addition to the general CDL requirements, there are also specific endorsements that may be required to operate certain types of commercial vehicles, such as trucks with air brakes. The Air Brakes (L) endorsement is required to operate any CMV equipped with air brakes. To obtain the L endorsement, you must pass an additional knowledge test and demonstrate your ability to operate a CMV with air brakes safely.
It is important to note that the CDL requirements and regulations may vary from state to state, so it is always best to check with the Maryland Department of Transportation (MDOT) Motor Vehicle Administration (MVA) for the most up-to-date information on CDL requirements and endorsements.
